Benefits of technology
The present invention is a power-assisted folding knife that uses an assisting mechanism to make it easier to unfold and operate with one hand. The knife has a locking mechanism to ensure safe use and a blade that can be locked by rotating it in a straight line. Additionally, the blade and handle have a moment balance generated by a limit piece and the elastic member, which ensures the blade is securely locked in both the folded and unfolded positions. The power-assisted folding knife has two assisting mechanisms to provide more ease of use and enable users to operate with one hand.
Problems solved by technology
Conventional folding knives typically require two hands to unfold or fold, and a relatively large force is needed during operation by users.

The present invention provides a power-assisted folding knife, comprising a handle, a blade, a locking mechanism, an assisting mechanism and a second assisting mechanism. The blade is rotatably connected to the handle. The locking mechanism and the second assisting mechanism are provided inside the handle. The assisting mechanism is connected to the handle and the blade respectively. When the blade is in a folded position, the assisting mechanism and the second assisting mechanism are used for locking or unlocking the blade. When the blade is in an unfolded position, the locking mechanism is used for locking or unlocking the blade. When the power-assisted folding knife is unfolded, the assisting mechanism and the second assisting mechanism provide assisting force for the blade and / or the handle.
Description
FIELD OF THE INVENTION[0001]The present invention relates to hand tools and in particular to a power-assisted folding knife.DESCRIPTION OF THE PRIOR ART[0002]Conventional folding knives typically require two hands to unfold or fold, and a relatively large force is needed during operation by users.[0003]The person skilled in the art endeavors to provide a power-assisted folding knife allowing for easier and efforts-saving unfolding of the folding knife, so that a user can operate it with one hand.SUMMARY OF THE INVENTION[0004]One object of the present invention is to provide a power-assisted folding knife which adopts an assisting mechanism to provide an assisting force upon unfolding the folding knife to enable easier unfolding and single-hand operation of the folding knife. The power-assisted folding knife has a locking mechanism capable of locking a blade holder in an unfolded position, ensuring safe use of the power-assisted folding knife.[0005]To solve the above technical proble...
